Specification of Letters Patent.

Patented Jan. 28, 1908.

Application filed May 13' 1907- Serial No. 373.386.

T 0 all whom it may concern:

Be it known that I, IilERBERT E. BROWN, a citizen of the United States, residing at Gold thwaite, in the county of Mills and State of Texas, have invented a new and useful Gearing for WVindmills, of which the following is a specification.

This invention relates to gearing for wind mills and has for its object to provide improved means for converting the rotary mo-' tion of the wheel shaft into a reciprocating motion thereby to operate the pump rod.

A further object of the invention is to provide a wheel supporting frame in which is mounted for vertical movement the pump actuating rod, the latter being provided with a vertically disposed rack adapted to engage a pinion on the wheel shaft so that when the wheel is rotated by the action of the wind the pinion will engage the rack and thus impart a reciprocating motion to the pump rod.

A still further object of the invention is to generally improve this class of devices so as to increase their utility, durability and elliciency.

Further objects and advantageswill appear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.

in the accon'ipanying drawings forming a part of this specification: Figure 1 is a side elevation of the upper portion of a wind mill gear constructed in accordance with my invention. Fig. 2 is a front elevation of the rack and its associated parts. Fig. 3 is a transverse sectional view taken on the line 3-3 of Fig. 2.

Similar numerals of reference indicate corresponding parts in all of the figures of the drawings.

The improved wind-mill gear forming the subject matter of the present invention includes a substantially rectangular supporting frame 5 having alined openings 6 formed therein for the reception of the pump rod 7.

Secured to one side of the frame 5 is a vane 8 and journaled in a bearing 9 on the opposite side of the vane is an operatin shaft 10 carrying a wind wheel 11 of any approved construction.

Secured to the pump rod 7 and mounted for frame 5 is a movable frame 12, the latter being substantially elliptical in shape and pro vided with a marginal guide flange 13.

Projecting laterally from the center of the movable frame 12 is an enlargement 14 pref erably of the same height as the flange 13 and spaced from the latter to form a continuous guide groove 15 adapted to receive an anti-friction roller 16 mounted for rotation on the inner end of the operating shaft 10, as shown.

Threaded or otherwise detachably secu ed to the enlargement 14 of the movable ms inber 12 are a plurality of spaced pins 17 which constitute a rack and are adapted to engage the teeth on a pinion 18, the latter being keyed or otherwise rigidly secured to the operating shaft;

The inner ends of the pin 17 are preferably threaded at 19 in the enlargement 14, while the outer ends thereof are connected by a longitudinally disposed bar 20 which serves to limit the lateral movement of the pinion 18 and thus prevent the same from becoming disengaged from the pins 17 and also to give additional strength to said. pins.

The movable frame 12 is provided with spaced laterally extending arms 21 which. bear against stop collars or sleeves 22 secured to the pump rod 7 and are provided with circular openings for the reception of said pump rod so as to permit the frame 12 to oscillate on the pump rod in the manner hereinafter described.

The collars 22 are locked in position on the pump rod 7 by screws or similar fastening devices 23 so as to prevent the frame 12 from moving vertically of the frame 5 independently of the rod 7.

The arms 21 are reinforced and strength ened by the provision of diagonal braces 24 which extend from the outer ends of said arms to the rear face of the movable member 12 and are preferably over-lapped and rigidly secured to said member by a bolt 25.

The outer ends of the arms 24 are provided with segmental recesses which preferably engage the adjacent surface of the rod 7 so as to form additional bearing surfaces for the arms of the movable frame 12 and reinforce and strengthen said frame at its point of attachment to the pump rod. 1

It will here be observed that the operating vertical movement within the stationary l shaft 1() being relatively fixed with respect to the supporting frame, when the pinion 18 is rotated by the action of the wind on the wheel 11 said pinion will engage the pins 17 of the rack and elevate the frame 1.2 together with the pump rod.

When the pinion 18 reaches the upper end of the rack the guide roller 16 by engagement with the adjacent curved wall 26 of the frame 12 will cause the pinion to travel over the top of the rack and down on the opposite side thereof thereby imparting a reciprocat ing motion to the pump rod.

It will thus be seen that the shaft 10 being relatively stationary, the rack will. travel up on one side of the pinion 18 and down on the other, and that the movable frame 12 will oscillate on the pump rod 7 so as to permit the rack to be in constant engagement with the pinion.

From the foregoing description it is thought that the construction and operation of the device will be readily understood by those skilled in the art and further description thereof is deemed unnecessary.

Having thus described the invention what is claimed is:

1. In a device of the class described, a frame, a rod mounted for vertical movement on the frame, a substantially elliptical plate disposed within the frame and provided with an enlargement, a marginal guide flange, secured to the plate and spaced from the enlargement to form a guide Way, arms extending laterally from the rear of said plate for attachment to the rod, a rack carried by the enlargement, a wheel shaft journaled in the frame, a pinion secured to the wheel shaft and meshing with the rack, and an anti-friction roller ournaled on the end of said shaft and engaging the guide-way.

2. A device of the class described including a frame, a rod slidably mounted for vertical movement within the frame and provided with spaced collars, a plate secured to the pump rod and provided with laterally 6X tending arms for engagement with said rod, braces connecting the arms and the inner face of the plate, a marginal guide flange extending laterally from the front of the plate, there being an enlargement formed integral with the plate and spaced from the flange to form a guide-Way, a rack secured to the enlargement, a wheel shaft journaled in the frame and provided with a terminal pinion adapted to engage the rack for reciprocating the pump rod, and an anti-friction roller carried by the wheel shaft and engaging the guide way.

3. A device of the class described including a frame, a rod slidably mounted for vertical movement on the frame, and an oscillating plate pivotally secured to and mounted for vertical movement with the rod, said plate being spaced laterally from and disposed parallel With. the rod, a marginal guide flange extending laterally from one side of the plate, there being an enlargement formed integral with the plate and spaced from the flange to form a guide-way, a rack secured to the enlargement, a shaft ournaled in the frame, a pinion carried by the shaft and engaging the rack for imparting reciprocating motion to the pump rod, and an anti-friction roller carried by the shaft and seated in the guide way. i

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
